Advances in periodontal diagnosis. 2. New clinical methods of diagnosis

This paper describes the new methods of periodontal diagnosis. An outline of the problems of periodontal probing techniques is followed by a discussion of the advances made by the use of constant pressure electronic probes. We finally highlight the problems of periodontal radiographical techniques, leading on to a description of computer-aided radiographic methods--in particular, digital subtraction radiology and computer-assisted linear radiology.
